In the twilight between sleep and consciousness, a battle rages. The Dream Guardians harness the energy created in slumber, even going so far as to fuel the sexual fantasies of those asleep to create maximum power.

For some reason, she recognizes him and knows his purpose...and still welcomes him into her bed. But just as their passion threaten to consume him body and soul, a danger lurks, for Lyssa is the Key that has been prophesized to destroy his world...
